[Elecraft] K3 FSK and psk

[Tom]

Hi
Thanks for the info Don. 
So in the case of the k3, when one enters a carraige return/ lf at the keyboard using the k3 utility,  the k3 translates this to hex 8 and hex2 and sends this over the air if using fsk?

Tom,

In ASCII code (used for PSK), LF and CR are two separate characters.  LF 
= hex "A" and CR = hex "D".
A true CR has no line feed associated with it, and a LF has no CR 
associated with it.
So it depends on the application doing the sending (and perhaps also on 
the application receiving) to determine just what happens.

You asked about FSK - and that is similar.  If you are analyzing the 
characters sent in BAUDOT code, the same thing applies but LF is Hex "2" 
and CR is hex "8*.

So if you are developing your own code, you will have to handle them 
separately.  Normally folks expect the "Enter" key on a keyboard to do a 
CR and LF while the down arrow does a LF only while the "home" key would 
do a CR only.  Applications normally follow those conventions, so if you 
are looking at it from a keyboarding standpoint, the Enter key should do 
both when using a normal application.

73,
